Fix Google Search Site Name Display Issue on Odoo Website

-I have an Odoo-based website with a persistent SEO display issue.

-In Google Search, the small grey line (site name line) above the blue title only shows the domain (e.g. msixxx.in).
It should show something like: "My Company Name Industries — msixxx.in".

-The blue meta title and description/snippet are showing correctly.

-I've already implemented:
Correct <title> tag
Proper meta tags like og:site_name
Valid structured data using @type: WebSite (via JSON-LD)
Google Search Console reindexing

-I need someone with:
Strong Odoo website development skills
Experience fixing SEO/meta/structured data issues
Ability to audit and debug custom code conflicts

Goal: Make sure Google displays the correct site name (not just domain) in the search result line above the title.
